Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
if there is poor visibility, e.g. due to snow,
R
rain, fog or spray
if the area of the windscreen around the
R
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
road users that have no lighting, e.g. pedes-
R
trians
road users that have poor lighting, e.g.
R
cyclists
road users whose lighting is not clearly visi-
R
ble, e.g. road users behind a crash barrier
on rare occasions: road users that have
R
lights that may be recognised too late or not
at all
